Benefits of technology
The present invention aims to provide a vehicle light with a good line-shaped appearance. More specifically, it integrates multiple rear lens units, making molding easier compared to all-in-one molding. Additionally, it prevents the formation of dark spots between the first and second rear lens bodies where light does not pass through. This is achieved through the use of a rear lens unit with a light exiting region that allows for diffused light to pass through.
Problems solved by technology
However, in Patent Document 1, there is a problem in that arranging a plurality of lens bodies adjacent to each other in a row causes boundary lines to be formed between the adjacent lens bodies and those boundary lines are visually recognized as if the front lens body is segmented, which results in an unfavorable line-shaped appearance.

Embodiment Construction
[0041]A vehicular lamp 10 (corresponding to a vehicular headlamp according to the present invention) according to an embodiment of the present invention is described below with reference to the attached drawings. Corresponding components in each drawing are denoted by the same reference symbols and overlapping descriptions are omitted.
[0042]FIG. 1 is a perspective view of the vehicular lamp 10. FIG. 2 is a top view of the vehicular lamp 10. FIG. 3 is a front view of the vehicular lamp 10.
[0043]The vehicular lamp 10 shown in FIGS. 1 to 3 is a vehicular headlamp (headlamp) and is mounted to, for example, the left and right sides on the front end of a vehicle such as an automobile. Because the vehicular lamp 10 to be mounted to both the left and right sides has a symmetrical configuration, a vehicular lamp 10 mounted to the left side at the front of a vehicle (left side facing the front of the vehicle) is described as a representative example of the vehicular lamp 10. Although not illu...

Abstract
A vehicular lamp comprising a front lens body extending in a predetermined direction, and a plurality of optical systems disposed along the predetermined direction behind the front lens body, the plurality of optical systems each includes a rear lens unit disposed behind the front lens body, and a light source which is disposed behind the rear lens unit and emits light which is irradiated forward permeating the rear lens unit and the front lens body in that order to form a headlamp light distribution pattern.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based upon and claims the benefit of priority of the prior Japanese Patent Application No. 2017-254082, filed on Dec. 28, 2017, the entire contents of which are incorporated herein by reference.FIELD[0002]The present invention relates to a vehicular lamp. More particularly, the present invention relates to a vehicular lamp that has a good line-shaped appearance.BACKGROUND[0003]There is known a vehicular lamp which employs a lens body integrally molded of a front lens unit and a rear lens unit disposed behind the front lens unit (see, for example, Patent Document 1 (FIG. 16, etc.)). The rear lens unit is a lens unit responsible for condensing light in a first direction (for example, a horizontal direction), and the front lens unit is a lens unit responsible for condensing light in a second direction orthogonal to the first direction (for example, a vertical direction).[0004]In Patent Document 1, a vehicular lamp that has...
